@ari Actually a few weeks to a month on 2 AAs depending on usage. The processor is a low power CMOS 80186 and the hardware is generally optimized for saving energy. HP was very good at that, an HP 48g calculator will run for years on 3 AAAs, compared to maybe one year on 4 AAs on a TI-83.

@ajroach42 Nice! I don't know much about the OmniGo, I think it isn't quite as PC compatible as the LX series? 200LX and OmniBook are fun, currently I'm working on getting parts to build 200LX serial cables because the cheapest I can find them is $40 + shipping.

@lroopThe omnigo has a lower resolution screen, and runs geos by default. It uses the same serial cable. It can do textmode dos stuff, but it takes digging through archives of German websites to find the appropriate software.

I'm working on putting together a complete toolkit with instructions but that'll be a few weeks down the road.
